Musical choices/genres: Rock - Not picked. A bit too loud to use, not conspicuous enough, although audience like that music it wouldn't work, but the possibility of using a ballad-like rock song to show subtlety.
Drum and Bass - Not picked. Too high paced, not enough subtlety, not classy enough.
Classical/Orchestral - Yes. Very subtle, builds tension, suits the genre. Only problem is can get too crowded out with all the instruments and can be hard to compose.
Metal - Not picked. Not suited as well, very loud, easy to use compared then others but is not subtle or doesn't build tension on bit.
Experimental - Not picked. Too random, too hard to use and compose, least subtle and inconspicuous music I can recall.
